Which McDonald's character served as the elected mayor of McDonaldland?

Mayor McCheese served as the elected mayor of McDonaldland.

Mayor McCheese was one of the central characters in McDonald's McDonaldland advertising. He had a human-like body, wore formal mayoral clothing, and had a large cheeseburger for a head. The design turned a familiar menu item into a recognizable civic character.

The character appeared alongside Ronald McDonald, the Hamburglar, Grimace, and other figures in commercials and promotional material. His role added a community structure to the fictional setting, making McDonaldland seem like a complete town rather than a collection of unrelated mascots.

Mayor McCheese is sometimes confused with Officer Big Mac or Captain Crook, who had different roles in the same advertising universe. Mayor McCheese was specifically the town's mayor, while the others represented different comic character types.
